Report on Mass Fish Death Released

Andy Fell — March 01, 2023 - 1:00pm

An independent investigation has found that a catastrophic fish mortality event at the �°��ϲ��Ļ��Ϣ Davis Center for Aquatic Biology and Aquaculture in August 2022 was caused by accumulation of mineral deposits inside sealed piping carrying wastewater away from the facility. This blockage caused chlorine, added to effluent water as a disinfectant, to back up to a water line used to lubricate pumps at the well supplying the fish tanks, and thus contaminate the tanks.

Reef Fish Evolution Driven by Biting

Andy Fell — July 27, 2022 - 9:40am

Coral reefs are home to a spectacular variety of fish. A new study by biologists at the University of California, Davis, shows that much of this diversity is driven by a relatively recent innovation among bony fish — feeding by biting prey from surfaces. The work is published the week of July 25 in Proceedings of the National Academy of Sciences.

‘Unfold’ Podcast, Episode 2: ‘Nature Tells Its Story’

Katherine E Kerlin — October 05, 2021 - 9:45am

A fish can’t talk, but its eyes and ears can. Scientists have discovered that each layer of a fish’s lens reveals a different part of its life history, including what it’s eaten throughout its life. While you’ve probably never heard of fish otoliths, these ear bones tell us not only a fish’s age, but what rivers it has traveled. Understanding this could help wildlife managers know what habitats to protect to help imperiled species.
